Hi,
We are looking at using the GnuRadio system in a signal processing system
we are designing. One of the requirements is for a butterworth filter.
Does anyone have any sugestions on how to implement this using the
GnuRadio system ?
I note there is an IIR filter implementation "gr_iir_filter_ffd", but
is there a good way to generate the required tap coefficients ?
There is code for this on Tony Fisher's filter design site.
Incorporating that into GNU Radio would be great.

Hi Matt,
Thanks for the info. I will have a look at the code and see if I
can integrate it.
